BCG not going into receiver

[331coupe]

What would cause BCG A. to fit into one receiver but not another one, but BCG B. and C. will fit into the receiver BCG A. wouldn't. Hope that makes sense lol. and I mean like won't even go an inch into the receiver.

The Bolt. The Bolt must be forward. The firing pin retaining pin must be all of the way in. The gas port on the BCG goes inside the charging handle. Does this help?

I just dont understand what the bolt would have to do with it tho?

After you assemble the BCG, pull the bolt all of the way forward before putting the BCG into the upper receiver

I feel like yall both missed the part where I said it fit into another receiver. I'm not a moron I realize the cam pin has to be in the right spot with the bolt pulled out. The literal carrier itself is being held and won't go in the receiver but a half an inch....yet goes in another receiver just fine. Link me to a YouTube video that describes this issue and I'll watch it gladly

Swap charging handles and see if you still have the problem

Tolerance stacking. You have two parts that are at the edge of tolerance.
